SU915971A1 - Hydrocyclon in-take filter for pump suction pipeline - Google Patents

Description

The invention relates to the devices you use in agriculture, which can be installed on the top of the suction pipe of the pump to catch sediment and floating bodies when drawing water from open water sources for irrigation.

Closest to the present invention is a hydrocyclone intake filter containing a cylindrical chamber and two oppositely directed cylindrical sockets, 'attached to the ends of the cylindrical chamber, a drain perforated pipe, a chamber for collecting clarified water, sand piping and hydraulic elevator, the base pump [1].

A disadvantage of the known device is the lack of elements for trapping and removal of floating bodies.

The purpose of the invention is to improve the quality of irrigation water purification from

open sources with abundant sediment and floating bodies.

This goal is achieved by the fact that the filter containing a cylindrical chamber and two oppositely directed cylindrical sockets attached to the ends of the cylindrical chamber, a drain perforated pipe, a chamber for collecting clarified water, sand pipes and a hydraulic elevator, the base pump, is equipped with hinges inside the drain perforated pipe augers with the possibility of rotation under the action of a drain flow of liquid, and the hydraulic elevator is located under the chamber of collection of clarified water and is hydraulically connected to the drain perforated pipe and sand nipples

The hydrocyclone intake filter contains a cylindrical chamber 1, cylindrical conic sockets 2, inlet pipes 3, drain pipes 4, a common perforated drain pipe 5, sand pipes 6, a chamber for collecting clarified water 7, a pipe for draining floating bodies (plankton) 8, a solid collecting screw 9 mounted on ball bearings 10 with a stand, suction pipe 11, pump 12 with discharge pipe 13, hydraulic elevator 14 with a water supply pipe 15 and pulp discharge 16.

The principle of the filter is as follows.

The filter is installed on the top of the pump suction piping. Fill the pump and start it up. The flow of fluid, along with sediments and floating bodies, after entering through the inlet nozzles 3 into the chambers of cylindrical cones 2, acquires a rotational motion. Under the action of centrifugal forces, the sediments are thrown to the sand nozzles 5, and the floating bodies, together with the clarified part of the water, are directed through the drain nozzles 4 into a common perforated drain pipe 5.

The clarified water through the pipe 5, the camera collecting the clarified water 7 and the suction pipe 11 pumps the pump. When this screw 9, rotating under the action of the fluid mass entering the sockets, continuously cleans the inner surface of the perforated drain pipe from the floating bodies (planktons) and leads them to the side of the pipe 8. Their pipes 8 are sucked away and dumped into the channel, below the pumping solution installation. The hydraulic elevator simultaneously produces ejection of pulp from the sand pipe

o cylindrical constricts 2. Working water is supplied to the hydraulic elevator through pipe 15 from the discharge pipe 13 of the pump 12.

The proposed hydrocyclone intake filter produces both sedimentation of sediments and trapping of floating bodies. It is simple in design, easy to use. Putting it into practice will make it possible to reduce the operational costs associated with carrying out measures to combat sediment and floating bodies by a factor of 2-3.
